The centrifuge is a common equipment in the drilling solids control system and the mud zero discharge system, so what is the difference between the centrifuges in the drilling solids control system and the mud zero discharge system?
Centrifuges in Drilling Solids Control Systems
The centrifuge in the drilling solids control system generally adopts medium and low speed centrifuges. Since the drilling solids control system adopts multi-stage solids control equipment, when the drilling fluid is filtered and separated from the mud shaker to the true remover to the sand and mud integrated machine after three-stage filtration and separation, the particle size of the mud particles has become very small, and the configuration requirements of the centrifuge have become smaller. Medium and low speed centrifuges have been able to meet the needs of slurry pulping.
Centrifuge in Mud Zero Discharge System
The centrifuge in Mud Zero Discharge System generally adopts a high-speed centrifuge or a frequency conversion centrifuge, which is a high-end centrifuge. The Mud Zero Discharge System is composed of a drill cuttings dryer and a high-speed variable frequency centrifuge. The Mud Zero Discharge System is located at the end of the solids control system and is used to process the drilling cuttings tailings processed by the solids control system, so the proportion of drilling cuttings tailings is very large, the solid particle size is large; because the centrifuge is to undertake the mud processed by the drilling cuttings dryer, the particle size in the mud screened by the drilling cuttings dryer is very large, and the requirements for the centrifuge are very high. Therefore, it is more appropriate to use a high-speed variable frequency centrifuge.
